Is it possible to have a htmlEditor filed on a tab?

I have got it display in Main by changing to
$fields->addFieldToTab("Root.Content.Main", new HTMLEditorField('TeaserText'), 'Content');

But on a tab is no go?

I can get tick boxes an whatever else, but can't seem to get a htmlEditor to display within a tab.

public static $db = array(

'TeaserText' => 'HTMLText'
);

function getCMSFields() {
$fields = parent::getCMSFields();

$fields->addFieldToTab("Root.Content.RightContent", new HTMLEditorField('TeaserText'), 'Content');

return $fields;
}

It could be because you're trying to insert the field before the 'Content' field but no field called content exists on that tab. Try not inserting the field above anything and see if it appears.

$fields->addFieldToTab("Root.Content.RightContent", new HTMLEditorField('TeaserText'));

fantastic that worked. Many thanks

I thought the second 'Content' bit was giving it a label rather than ordering.

No, to give it a label you need to pass 'Content' as the argument to HTMLEditorField.

$fields->addFieldToTab("Root.Content.RightContent", new HTMLEditorField('TeaserText', 'Content'));
